Improve both the sound and the power from your 981 Boxster/Cayman with these sport headers. Our Sport Headers use 200 cell HJS catalytic converters which improve exhaust flow while still cleaning your exhaust gases.


These headers will give you a significant increase in volume, and a smooth sports car sound.


These dyno designed headers feature smooth mandrel bends and a 3-1 collector to get the most power out of your 981. Paired with a Maxflo Exhaust at 6600 RPM there we saw an increase of 13 whp and 10 ft/lbs of tq and these gains are carried throughout the rev range for great under the curve power.


  • Fits Porsche 981 Boxster/Cayman Base, S, and GTS vehicles (2013-2016)

  • Includes German-imported 200-cell HJS Sport Catalytic Converters for maximum performance

  • European homologated EURO 6 special catalytic converters. No Check engine light guaranteed

  • Optimized for maximum performance with NO check engine light, guaranteed

  • Adds 13 whp at 6600 RPM and 21 ft/lbs of tq at 3300 RPM when combined with the Maxflo Performance Exhaust System

  • Saves 6 lbs from the rear of the vehicle compared to the full OEM headers

  • Constructed from equal-length T304 stainless steel C.N.C. mandrel-bent tubing for improved torque and equalized engine pulsing

  • More power and torque across the RPM band and dramatically improved sports car sound

  • Includes multi-layer exhaust manifold gasket

  • Direct bolt-on replacement for the OEM headers with no cutting or welding required

  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

Why We Choose HJS Catalytic Converters: 

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.    

Designed to be the perfect complement to either the factory exhaust system or Fabspeed’s Maxflo or Supercup Exhaust systems, these high-flow headers include HJS catalytic converters, making them the best upgrade for street driving and emissions compliance.

INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.

DISCLAIMER: This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product contains a High-Flow Sport Catalytic Converter solely intended for track and race cars as it is NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.

    Awesome Upgrade, Excellent Quality & Performance

    Posted by James Winner, Milwaukee on 8th Feb 2018

    Customer service was fantastic, had answers for all of my questions. The Sport Headers arrived packed in form-fitting foam so there was no chance of shipping damage. The quality was outstanding, the welds clean, and quality control stickers with signatures were attached. Since installing these headers I have experienced a better jump off the line and more pulling power throughout the rev range. Very satisfied customer, cannot wait to complement the headers with the Maxflo exhaust.

    Amazing Sound, Amazing Difference, Different Feel and Character

    Power and throttle response changes and car feels different in a positive way. The Setup I have with the Plenum + Throttle Body + COBB Tune with the all new PDK tune is brilliant, now the car feels just right for daily use.

    981 Cayman S

    The headers are consistent with everything I have heard from you, your website, and comments from other club and forum members. Bottom line is I am well pleased with the results. Both my Porsche mechanic/machinist friend and I were impressed with the build quality and the performance results which eliminated the classic flat spot in the horsepower/torque curve. The extra pulling power from the added horsepower was just icing on the cake. Thank you again for your time and for the information you provided. On another note, I understand that the owner of Fabspeed is a good friend of another friend of mine, Dudley Wass. Dudley was my driving instructor for a number of PCA events. We spoke recently about the 911s and Caymans we have owned over the years..and I received yet another endorsement for Fabspeed products in the process.
